“Do the best you can until you know better. Then when you know better, do better.” - Maya Angelou. We often wait when we don't know what to do because we've seen others do things better. Don't let the accomplishments of others intimidate you.
Do the best you can with what you know now. You'll learn more later. You'll learn more from doing. When you learn, then you can do better.
This pretty much sums up the Lifehacker MO.
